Divje Jezero (Wild Lake) is a huge deep blue karst spring, the emergence of the Jezernica river, which flows after only 50 m into the Idijca river. The spring is a collapse doline, the end of a cave system which drains the mountains to the south. The cave below the lake goes down rather steep. It is explored for 160 m, going down 83 m deep. The big depth is an enormous problem for human divers and so exploration has come to an end.
The cave was formed along a tectonic fault, which is visible in the rock face behind the spring. But this is not only a geologic site. The flora and fauna around the spring is exceptional and protected. There are also Olms (Proteus anguinus) living in the cave, which are sometimes transported out by floods. At normal times the fresh water is full of trout.
The lake is a famous tourist destination, although it is off the major tourist routes. It is primarly visited by Solwenian tourists. The spring is only a few meters from the road and the parking lot. Trails on both sides of the Jezernica lead to the spring and around. The trail is very bad in places, but it is possible to reach the lake without problems. For a complete round trip we recommend good shoes.
